Error: 'Invalid value used in weak set' in Nestia Swagger Generation After Introducing PrismaModule

[Val0429]

Firstly thanks for the excellent work! It works very well and we decided to put nestia into our code base.

Summary

The bug manifests during the Nestia Swagger generation process. Initially, it ran smoothly until I added a straightforward PrismaModule following the official NestJS documentation. Strangely, even without importing it explicitly, the Swagger generation now throws an error: "Invalid value used in weak set."

• SDK Version: [email protected], [email protected], [email protected]
• Expected behavior: npx nestia swagger should generate successfully
• Actual behavior: npx nestia swagger shows error "Invalid value used in weak set."

I've made a github project to demonstrate this bug.

git checkout 75d577c: It's the code which works

git checkout main: Not working

At first, change input property of nestia.config.ts file to be src/**/*.controller.ts like below, then you can avoid the bug.

For reference, the reason of the bug is occured by below code, and such WeakSet cannot store string value what you've exported through prisma.module.ts file.

I'll fix this bug ASAP. Thanks for special reporting.

Change nestia.config.ts file like below

My code occuring the bug

nestia/packages/sdk/src/analyses/ReflectAnalyzer.ts

Lines 15 to 39 in e995adc

	export namespace ReflectAnalyzer {
	export async function analyze(
	unique: WeakSet<any>,
	file: string,
	): Promise<IController[]> {
	const module: IModule = await (async () => {
	try {
	return await import(file);
	} catch (exp) {
	console.log(
	">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>",
	);
	console.log(`Error on "${file}" file. Check your code.`);
	console.log(exp);
	console.log(
	">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>",

	process.exit(-1);

	})();
	const ret: IController[] = [];
	for (const tuple of Object.entries(module)) {

Your prisma.module.ts file

export const PRISMA_INJECTION_TOKEN = "PrismaService";
